Can you make Mountain Dew glow simply by adding some baking soda and hydrogen peroxide to it? That's what this video claims. I was so excited after watching it that I was all prepared to go out, buy a bottle of Mountain Dew, and try the experiment myself. Thankfully I didn't, because the video is a fake. If you watch it closely, you can see that a break occurs after the person pours the Mountain Dew into the glass. During this break is when the contents of a glow stick were added to the Mountain Dew bottle. According to Wikipedia, hydrogen peroxide serves as an activating agent for the glow-stick dye. "It reacts with the ester to form an unstable CO2 dimer which excites the dye to an excited state; the dye emits a photon (light) when it spontaneously relaxes back to the ground state." I don't know what the purpose of the baking soda is.
